Hi Berry, Yes, this policy of non-support of Oracle on virtual systems applies to VMware as well. That is why we still run our main Oracle on Sparc iron. Political trouble ahead.... ;-)

So when a (performance) problem is found they first advise to migrate to a dedicated server, and increase resources, before they attempt to solve the problem. This is not (only) true for z but also for other virtual systems as well, we discovered this because of the advice to migrate off of cloud systems. So basically any 'cloud' service is not advised to run Oracle. Even more so, Oracle 'must' be installed with HA , the server 'must' have 4G to install in the first place and even more to run the database. Obviously plenty of caching must be available on all levels (FS cache, SGA/PGA, shared segments etc) to 'improve' performance. Needless to say that this makes server 'virtual unfriendly' to say the least, impossible to run virtualized would be a better description. Can anyone confirm this statement? Is it Oracle or is it the interpretation or our Oracle group? Is there a formal statement from Oracle itself? (And Yes, we do run Oracle systems. And we do measure the best performance in systems that are as small as possible, ie don't run according to Oracle recommendations. So from our point of view the statement is not true but that doesn't help if there is no support on whatever level.)
